Using Qt's QDirIterator with FTP server

Question

(Using Qt 4.7) I have a function that needs to take a user input of a directory name, then loop through files in a directory by that name on an FTP server. The ftp address is constant so I have it hard-coded in. So far I have this:

QString dir_name = /*whatever the user inputs*/;
QString source = "ftp://username:password@ftp.myftpaddress.com/" + dir_name + "/";
QDirIterator it(source, QDirIterator::NoIteratorFlags);

while(it.hasNext())
{
  //do things with each individual file...
}

However, when I run this it never enters the loop. I put in print statements to help debug and it keeps saying that the directory referred to by it is empty, even though it isn't. I tried simply copy and pasting the result for source into a browser and it is correct. I have used both FTP servers and QDirIterator before but never together, is there something special I need to do to get it to work?

QDir only works for local files/anything mapped transparently into the file system by the OS. — Frank Osterfeld, Sep 27 '13 at 13:08
Is there any other way to do this in that case? I've been trying to figure it out for a while and sort of striking out — thnkwthprtls, Sep 27 '13 at 13:09
I have also tried using QFtp to access it but it still comes back empty — thnkwthprtls, Sep 27 '13 at 18:16
QNetworkAccessManager. Using blocking API to operate with remote hosts wouldn't be very useful in a UI application. — Frank Osterfeld, Sep 28 '13 at 07:29

Nothing special, it just will not work because QDirIterator works with local files. It does not support network drivers as such. You would need to handle the iteration yourself.

I am sorry for being the worse news.
